Abstract

A catalyst for catalytic oxidation-deoxidation method of unsaturated hydrocarbon-containing gas has a carrier, an active component, a first co-agent component, and a second co-agent component loaded on the carrier respectively. The active component is one or more selected from the group consisting of oxides of Pt, Pd, Ru, Rh, Ag and Ir. The first co-agent component has one or more selected from the group consisting of a rare earth metal element, a group IVB metal element and a group VIII metal element; and the second co-agent component has one or more alkali metal element and alkaline earth metal element. The deoxidation method using the catalyst eliminates the need to add a reducing gas such as H₂, allows hydrocarbons to react directly with oxygen to produce CO₂ and H₂O, achieves the goal of deoxidating a hydrocarbon-containing tail gas, and can prevent the generation of carbon deposits.
